Problems solved by technology

However, because the raw material for the production of machine-made sand is not viscous, it can only form the skeleton of the interface mortar. The viscosity of the interface mortar currently on the market basically depends on the presence of cement and other additives to exert the bonding effect of the interface mortar.

Abstract

The invention provides dry-mixed interface mortar and a preparation method thereof. Hectorite and halloysite are added into a self-made machine-made sand to increase the viscosity of the sand, thereby having viscosity while forming a mortar framework, and enhancing the overall viscosity of the mortar. Fly ash is doped, so that the mortar has crack resistance. The hardness of the nano silicon oxide is high, and meanwhile, attachment points are increased. Silica sol is added into machine-made sand particles and cured to form a firm gel structure, and the viscosity is generated. The modified latex powder improves the adhesive property, has certain thickening property and permeability, and can permeate into two adhered wall bodies to shrink pores and cracks, thereby improving various properties such as surface hardness, impermeability, wear resistance and the like, and effectively preventing dry shrinkage and cracking of the mortar. Nano glass fibers improve the curing effect of the mortar. The coagulant adjusts the coagulation speed of the mortar, so that the density of the mortar is increased, and the strength is improved; The mortar is prevented from cracking due to the existence of a water-retaining agent component.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a dry-mixed interface mortar. [0002] technical background [0003] Interface mortar, also known as interface agent, is often used to treat the surface of concrete, aerated concrete, lime sand brick and fly ash brick, especially the bonding between large-scale poured concrete and insulation layer, to solve the problem of excessive water absorption of these surfaces Low adhesion, hollowing, cracking, peeling and other problems caused by strong, smooth or different media. The interface mortar is a single component, which is applied on the wall to enhance the adhesion of the base. It can replace the traditional concrete surface chiseling process, improve the plastering process of the aerated concrete surface, improve the connection between the concrete surface base and the insulation layer, and can improve the quality of the project, speed up the construction progress, a...
